+## Libra-Chat
+This model was further finetuned with instructions based on Libra-Base for multi-modal chat.
+
+### !!! NOTE !!!
+In addition to the pretrained weights in this repo, please download the pretrained CLIP model in huggingface and merge it into the path, as:
+
+```
+libra-chat/
+├── ...
+└── openai-clip-vit-large-patch14-336/
+    └── ...    
+``` 
+
+The CLIP model can be downloaded [here](https://huggingface.co/openai/clip-vit-large-patch14-336).
